Process Flow Chart

- World’s first SLA super hydrophilic surface made by dry process

- Hydrophilicity by activation with Alkali Rinsing Solution & Nano Ca/P coating

- Macro-pore & Micro-pore of Ti-Oxide layer mimicking the etched enamel rod of tooth

- Even Distribution of roughness through the whole portion of Implant Surface

▶ Acceleration of Osseointegration Maximization of BIC (Bone to Implant Contact) * SLA-SH is applied for All of Cowellmedi Implant

SLA-SH® : Roughness

Ra=1.8um

Why is Roughness of Surface Important ?

• Proliferation of cells

• Enzyme activity of calcification Osteoblast

• Phago-cytosis acitivity of injury bone

• Remodeling of trabeculae Osteoclast

Nucleating and mineralizing ability of the implant surface

Conclusion

- Surface treatment pattern were observed on electron microscope photographs of 5000 magnifications for the implants.

- Defects of sandblasted surface conditions were observed in Sample A,B, and C due to insufficient acid etching patterns in deep parts.

- The entire surface of INNO Implant treated with SLA-Bioactive® showed uniform acid atching patterns.

- This implies that the sandblasting and acid etching method of Cowellmedi’ SLA-Bioactive® is perfect.

Surface abrasive resistance in high torque placement

• Fixture placement torque 45 and 80 N/cm

• The micro-structure of titanium oxide layers in the crestal, middle and apical

threads are maintained without the abrasion and defect.

World’s Cutting Edge Surface Treatment : Super Hydrophilicity

SLA = 143° Hydrophobic Effect by air contamination

SLA+Neutralization = 36° ⇒ Hydrophilic

SLA + Neutralization + Na/Cap= 9°

⇒Super Hydrophilic

Surface Energy Maxmization

Calcium ions hydrothermal treatment

Why is Hydrophilicity of Surface Important ?

1. Faster Osseointegration

- Earlier Bone Formation - Better Stability from faster osseointergration

2. Higher Success Rate

- Higher Success Rate - Ideal for Immediate Placement

3. Super Hydrophilicity by dry process

- The first surface in the world made by dry process - Application of surface reforming & surface energy maximization

4. Chemical Activation (Cell Reaction)

- Cell Reaction beginning upon placement - Chemically Optimized Activation

Super Hydrophilicity of SLA-SH

• Bioactive Osteo-conduction

• Complete Resorption

Alkali Rising Solution

Nano Ca/P layer

The water contact angle of SLA-SH® hydrophilic surface becomes 9° after Nano Ca/P Coating & NaOH Solution rising and Hydrophilicity is well maintained.

(In static water contact angle measurement, the water contact angle below 40° means hydrophilic and below 10° is extremely hydrophilic)
